Abstract

This document describes two Fully-Specified Forward Error Correction
(FEC) Schemes, Low Density Parity Check (LDPC) Staircase and LDPC
Triangle, and their application to the reliable delivery of data
objects on the packet erasure channel (i.e., a communication path
where packets are either received without any corruption or discarded
during transmission). These systematic FEC codes belong to the well-
known class of "Low Density Parity Check" codes, and are large block
FEC codes in the sense of RFC 3453. [STANDARDS-TRACK]
